Fluctuating force-coupling method for interacting colloids

This paper was presented at the 4th Micro and Nano Flows Conference (MNF2014), which was held at University College, London, UK. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute, ASME Press, LCN London Centre for Nanotechnology, UCL University College London, UCL Engineering, the International NanoScience Community, www.nanopaprika.eu.Brownian motion plays an important role in the dynamics of colloidal suspensions. It affects rheological properties, influences the self-assembly of structures, and regulates particle transport. While including Brownian motion in simulations is necessary to reproduce and study these effects, it is computationally intensive due to the configuration dependent statistics of the particles’ random motion. We will present recent work that speeds up this calculation for the force-coupling method (FCM), a regularized multipole approach to simulating suspensions at large-scale. We show that by forcing the surrounding fluid with a configurationindependent, white-noise stress, fluctuating FCM yields the correct particle random motion, even when higherorder terms, such as the stresslets, are included in the multipole expansion. We present results from several simulations demonstrating the effectiveness of this approach for modern problems in colloidal science and discuss open questions such as the extension of fluctuating FCM to dense suspensions

Atomic force and scanning electron microscopic investigation of the in operandi creation of selective sites on MoO3 mixed with alpha-Sb2O4 in the isobutene to methacrolein oxidation

We show that the creation of selective sites on MoO3 due to remote control effects, has, as a counterpart, the spillover-induced reconstruction of the non-selective (010) faces of MoO3 crystals in selective (100) pits and steps. The phenomenon is observed both at the micrometric scale, by SEM, and at the nanometric scale, by AFM. (C) 1997 Elsevier Science B.V

Prospects of Genetics and Epigenetics of Alcohol Use Disorder

Purpose of Review: In this study, we illustrate recent findings regarding the genetics and epigenetics of alcohol use disorder (AUD). We further outline the future direction of genetic and epigenetic research in AUD. Recent Findings: Recent genome- and epigenome-wide studies allow new insight into genetic and epigenetic variation associated with AUD. The largest EWAS of AUD so far/to date found evidence for altered glucocorticoid receptor regulation. Longitudinal studies provide insight into the dynamics of the disease. Analyses of postmortem brain tissue reveal the impact of chronic alcohol consumption on DNA methylation in the brain. Summary: Genetic and environmental factors-mediated via epigenetic mechanisms-play an important role in AUD. Although knowledge of the biological underpinnings of AUD is still limited, ongoing research will ultimately lead to the development of biomarkers for disease classification, course of disease, and treatment response to support personalized medicine in the future
